ABSTRACT:
An improved lapping composition for use in lapping the surfaces of parts such as gears, seals, rings, and the like comprises a hydrocarbon liquid which is gelled by the addition of an alkyl orthophosphate gelling agent and to which is added the abrasive grit. The thixotropic character of the composition provides greatly improved suspension of the abrasive grit and highly desirable flow characteristics under shear, and results in an unexpected improvement in lapping rates.
